7 Claims. (Cl. 15-131) This invention relates to marking devices andparticularly to an improved impact-type marking device.

The invention is described as embodied in a paint hammer which includesa can of paint with an outlet neck of reduced diameter and a specialprotruding cushion applicator fastened to the neck of the can. The canis releasably secured to a handle and is intended to be used in mostinstances by striking it hammer fashion against the surface to bemarked.

Such a paint hammer, for example, can be used for marking trees, stacksof lumber, railroad ties, and many other articles where codedinformation may be recorded as a function of color or the number orarrangement of marks.

The various aspects, features, and advantages of the invention will bepointed out in or be apparent from the following detailed description ofa marking device incorporating the invention considered in connectionwith the accompanying drawings, in which:

Figure 1 is a perspective view of a paint hammer" incorporating theinvention; and

Figure 2 is an exploded perspective view of the applicator forming partof the device shown in Figure 1.

As shown in Figure 1, the paint hammer includes a handle 2, for exampleabout two feet long, arranged to support a container 4 which may befilled with paint or some other marking fluid. A somewhat perviousprotruding cushion applicator 6 is secured to one end of the container4.

In use the paint hammer" is held by the handle 2 and the applicator 6 iscaused to strike the article to be marked. This action forces a smallquantity of paint from the can 4 to penetrate the pervious applicator 6and be applied to the article struck with the applicator.

The can 4 can be formed of a standard screw-cap paint can or otherconventional container. As best shown in Figure 2 the applicator isformed of a perforated screw-type cap 8 which is covered by suitableporous material that permits the transmission of controlled amounts ofpaint and at the same time provides a cushion for absorbing part of theimpact when the article to be marked is struck.

Preferably the perforations 10 in the cap 8 are made by drivingsharp-pointed punches against the inner surface of the cap so as to formoutwardly extending barbs. The cushion, in the example, is formed byplacing three pieces 14, 16, and 18 of jute fabric, such as heavyburlap, of increasingly larger diameter over the perforations and barbsand securing these cushioning members by a cover 20 of mesh materialmade of loosely-knitted, heavy cotton thread or other suitable material.The cover mesh 20 is secured to the neck of the container 4 by anysuitable type of clamp formed in this example by a wire loop 22 in whichthe ends of the wire are twisted together to anchor the porous cover 20firmly in position and prevent leakage around the edges of the cover.

The cushioned structure of the pervious opening in the container permitsthe paint to be driven by impact ice through the fabric without damageto the surface being marked or to the paint container.

In order to protect the contents of the can 4 during shipping, a cap 24of foil or other flexible impervious material is placed over the cover20 and secured in position by a plastic band 26. Thus, it is onlynecessary to remove the band 26 and cap 24 to place the con tainer incondition for use.

The container 4 is mounted in a bracket 28 comprising an open-worksocket providing a cylindrical receptacle for receiving the container 4.This receptacle engages the sides and end of the container and could befully closed on the bottom and sides as desired. The bracket 28 issecured to yoke members 30 of the handle 2 and includes a pair ofresilient straps extending along the sides of the container with aninward hook releasably securing the container in place. The container 4thus may be positioned with its longitudinal axis substantially at rightangles to the handle 2, or it may be positioned at any other desiredangle. Once the position is selected it can be locked in position bymeans of wing nuts 32 on diametrically opposite sides of the cylindricalreceptacle.

What is claimed is:

1. An impact type marking device comprising a container for markingliquid, 21 screw-type perforated lid on the container, a plurality oflayers of pervious fabric positioned one on top of the other over saidperforations, successive ones of said layers being of graduallyincreasing diameter, and means holding said successively larger layersof fabric on said perforated lid forming a rounded cushion, saidsuccessively larger layers of fabric providing a cushion for absorbingimpact while transmitting controlled amounts of marking liquidtherethrough.

2. An impact type marking device comprising a container for markingliquid having a perforated screwtype cover of substantially smallerdiameter than the diameter of said container, three pieces of jutepositioned over said cover and being of successively increasingdiameter, the smallest diameter being adjacent said perforations, a meshfabric positioned over said jute and being drawn back tightly around thejute pieces and around the outer surface of said cover for shaping saidpieces of jute into a convex cushion on top of said perforated cover,and means securing said mesh fabric to said cover, said pieces of juteand mesh fabric providing a cushion for absorbing impact when struckagainst an article to be marked and transmitting controlled amounts ofmarking liquid therethrough.

3. An impact type marking device comprising a container for markingliquid having a perforated screwtype cover, a plurality of pieces ofjute positioned over said cover and being of successively increasingdiameter, the smallest diameter being adjacent said perforations, a meshfabric positioned over said jute and being drawn back snugly around theouter surface of said cover for holding said pieces of jute in a roundedpad, means securing said mesh fabric to said cover, and a handleextending at an angle from said container.

4. A ready-to-use impact type paint marking device including a containerfor paint having a perforated screwtype cover of substantially smallerdiameter than the diameter of said container, a plurality of perviousresilient layers of successively larger diameter over said cover forminga convex cushion adapted to transmit paint therethrough, a meshoverlying said convex cushion and the sides of said cover, a loop aroundthe sides of said cover overlying said mesh and securing said mesh inplace on the cover, and a cap of flexible impervious material overlyingsaid mesh and removably secured in place.

5. An impact-type marking hammer for marking 0b- 3 V jeets with paintand similar marking'fiuids by striking the objects to be marked inhammer fashion, said paint hammer comprising a handle adapted to be heldin the hand and swung in hammer fashion, a bracket secured to saidhandle, a container for paint and similar marking fluids held in saidbracket, said bracket including socket means engaging the sides and ,oneend of said container and including a resilient strap extending alongthe side of the container with an inward hook releasably engaging theopposite end of the container for holding the container in place in thebracket, said container and bracket effectively forming the head of saidhammer, said container having a protruding neck of reduced diameter atsaid opposite end thereof, and an impact cushion and applicator for themarking fluid on the neck of the container comprising a pervious cushionprotruding forwardly beyond the neck of the container.

6. An impact-type marking hammer for marking objects with marking fluidsby striking the objects to be marked in hammer fashion, said markinghammer comprising a handle adapted to be held in the hand and swung inhammer fashion, a yoke secured to one end of said handle, a bracketincluding a cylindrical receptacle adapted to hold a cylindricalcontainer therein,

means adjustably securing said bracket to said yoke for adjusting theangle of said bracket with respect to the handle, a cylindricalcontainer for the marking fluid releasably held in said bracket withsaid cylindrical recep tacle engaging the side and one end of saidcontainer,

and applicator for the marking-fluid protruding beyond the neck of thecontainer comprising a perforated member extending across the neck ofthe container and a pad of pervious material over said perforated memberand protruding forwardly.

7. An impact-type marking hammer as claimed in claim 6 and wherein saidmeans adjustably securing said bracket to said yoke are positioned atpoints on diametrically opposite sides of said container near the openend of said cylindrical receptacle, said resilient strap means extendingfrom said receptacle at said points,
